Description

Paper-free container in-mold forming free positioning structure

This creation department belongs to the field of paper containers, especially refers to the structural improvement of the sheet metal butt joint into the container body, which can be quickly and easily placed in the in-mold forming ring.

According to the progress of the times and the changes in the living habits of Chinese people, portable drinks such as coffee, juice, pearl milk tea and various tea drinks are extremely popular. Based on the convenience of carrying and cost considerations, the current portable drinks Generally, it is made of paper or plastic beverage cups. For paper cups or beverage cups, because of the paper structure, the structural strength of the paper itself is poor. Therefore, the original creation of the creator of this case is tied to paper. The edge of the material container cup is formed at the edge of the plastic material, such as the structure disclosed in the patent modification of the paper cup container of the patent number M390720 (hereinafter referred to as the conventional use case), including a cup body and a cup sleeve, the conventional use In the case, the plastic film injecting technology is used on the top edge of the cup to form a glued layer of decomposable plastic material to enhance the structural strength of the cup.

However, since the cup body is folded into a cylindrical structure by the two ends of the sheet-like paper, the two ends of the combined structure are overlapped (as shown in the first figure), so when the body is placed in the mold, the The positioning part (not shown) for the overlapping position of the mold is provided inside the mold, so that the mold can be clamped. Therefore, since the conventional cup is placed in the mold, the positioning operation must be performed. Not only does the quality of the glue layer have a large drop in quality, but also the work efficiency is low, and it is necessary to improve it.

In view of this, the creator has in-depth discussion on the above-mentioned practical creation issues, and actively seeks solutions through years of experience in R&D and manufacturing of related industries. After long-term efforts in research and development, he has finally succeeded in developing this creation. "The positioning structure of the in-mold forming of paper containers" to improve the problem of custom creation.

The main purpose of the present invention is to solve the above problems and provide a "free positioning structure for in-mold forming of a paper container", which requires the container body of the paper container to be placed in a mold for in-mold forming work without additional The positioning action to improve the efficiency and quality of the in-mold forming work.

For the purpose of achieving the above-mentioned effects, the present invention "the free positioning structure of the in-mold forming of the paper container" comprises a container body constituting a paper container, and the container system is formed by folding a sheet into a cylindrical structure. The container body is placed in a mold, and a rim portion of a plastic material is formed at one end of the opening by in-mold molding. Mainly before the sheet is folded into the container body, a notch is cut at a corner of the opening corresponding to the opening of the paper container, so that when the sheet is folded into the container body, the opposite end edges are end faces and end faces. The docking is such that the position for forming the rim portion exhibits a single toroidal structure without overlapping. Thereby, the container body can be placed in the mold to form and shape the rim portion, and the operation efficiency and quality of the in-mold forming can be improved without special positioning operation.

With regard to the techniques, means and functions of the present invention, a preferred embodiment is described in detail with reference to the drawings, and it is believed that the above objects, structures and features of the present invention can be obtained from an in-depth and specific understanding. .

The fourth picture is a schematic view of the three-dimensional appearance of the created plate.

The fifth figure is a schematic view of the creation of the sheet material into a container body.

Please refer to the second to fifth figures. The creation of the "paper-free container in-mold forming-free positioning structure" includes a paper container (1) which is under the container body (10). a bottom plate (20) is disposed on the bottom surface, and an edge of the upper opening (11) is formed by a rim portion (30), wherein the container body (10) is folded into a cylindrical structure by a plate (10'), and The sheet (10') is folded into the container Before the body (10), a notch (12) is cut at a corner corresponding to one end of the forming opening (11), the notch (12) being geometrically shaped, and the cutting distance is at least equal to forming the edge portion (30) The height. When the plate (10') is folded into the container body (10), the opposite end edges thereof can be joined in such a manner that the end faces and the end faces are butted, so that the position for forming the ring edge portion (30) is non-overlapping. Single toroidal structure.

The bottom plate (20) is a general paper sheet which is bonded to the bottom edge of the inner edge of the container body (10), which is a conventional technique and will not be described again.

The rim portion (30) is a plastic material which can be biodecomposed or a raw plastic material, and can be molded at the periphery of the opening (11) of the container body (10) by using an in-mold coating injection molding technique. In order to increase the structural strength of the paper container (1); the application of the in-mold forming technology has been applied for in another case and will not be described again.

With the above-mentioned component composition, the portion to which the container body (10) is butt-joined has a single-ring structure, and the container body (10) can be injection molded into the mold to form the rim portion (30) without additional The positioning action to improve the efficiency and quality of the molding operation.

In summary, this creation has its excellent progress and practicality in the same kind of products. At the same time, it has not found the same structure in the literature and the technical information about such structures at home and abroad. This creation already has patent requirements and is submitted in accordance with the law.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto; therefore, the simple equivalent changes and modifications made by the scope of the patent application and the contents of the specification are All should remain within the scope of this creation patent.
